What the rate table does not tell you

01

“With dependents” is a dependency status, not a marital status. A single member paying child support can be authorized BAH-Diff; a married dual-military couple with no children is not automatically the with-dependents rate for both. If your situation is unusual, your finance office decides — not this table.

02

O-8, O-9 and O-10 draw the same BAH as O-7. The table stops there for a reason, not because it is missing rows.

03

This is CONUS BAH only. Overseas is OHA, which works differently — it reimburses actual rent up to a cap, with separate utility and move-in allowances. Alaska and Hawaii are BAH; Germany, Japan and Korea are OHA.
